Blowby BAD, have RDT, blew out new rear main?

[6 Nebraska IDIs]

WTH?
Moms truck is the 94 turbo, and we cant figure it out, the RDT smokes like a fire, the turbo was full of oil before we RTD'd it, had the rear main leaking, so we replaced it. Now its leaking again?
We want to get rid of the RDT if at all possible but dont want to fill the turbo full of oil, but dont know what else to do with it?
Is this engine shot?
It barely has 100,000 in it

Excessive boost leaking around the rings. Pressurizes the crankcase. Oil everywhere.

I was told once that valve guides can cause this too if they leak.

The rear main seal on these engines seems to be a bad design. I think every truck I own including the PSD has a leaky rear main seal. If you just replaced it, it doubt the RDT is at fault.

From all the RDT and CDR threads I have seen here I have begun looking into a system I ran on my ole Ford Cortina.

I used a 1 way valve in the header collector, that used the exhaust pulse to create a negative pressure on a line connected to the valve cover.

Now I know this setup as a "Pan Evac or Sump Evac" system. Perhaps you know or have seen what I mean.

Well upon further research today on this subject I came across this here. http://www.dragstuff.com/techarticles/vacuum-pumps.html which uses a modified A.I.R. pump to create a negative pressure in the crankcase.

That being said, anyone who has converted to hydroassist brakes now has a pump that is doing nothing. Well maybe it's time we look into using the vacuum pump to do the same and get that RDT eliminated? Perhaps a small collection bowl, like on an air compressor water/oil trap between the pump and the engine could help to remove oil and keep the pump working longer?

The effect of negative pressure is longer seal life, better ring sealing, thus more HP n TQ as stated in the article above. Sounds like a win win situation.

What are your thoughts on this subject, lets put the collective genius together here and come up with a solid solution that helps everyone!

Schemes to suck the vapors out have been tried and failed. The key to a sucessfull RDT implimentation is to not suck or blow the vapors, but rather allow them to seek their natural level.
